  • Substantially rectangular openings 3 of a predetermined size and having preferably rounded corners are cut out of the flange member 1 immediately adjacent to the tubular portion 2,'such that one side of each of the openings 3 is disposed tangentially to the tubular portion 2.
  • the flange member 1 is preferably rectangular or oblong and preferably complements the shape of the openings 3.
  • Prongs 4 of a suitable, predetermined length extend from the tubular portion 2 in an axial direction opposite to that of the tubular portion 2 from each side 0f the center where the rectangular openings 3 meet with the centrally of the clinch nut disclosed Patented Feb. 21, 1967.
  • the end of the tubular portion 2, disposed opposite to the end to which the prongs 4 are attached, is equipped in the first embodiment, as disclosed in FIGS. 1 to 5, with a single formed thread 5.
  • the clinch nut designed in accordance with the present invention is adapted to be applied to a thin plate of metal, plastic, nylon, or the like, in a manner shown in FIGS. 3 to 5, of the drawings.
  • a clinch nut is to be secured to a thin plate 6
  • a round hole 7 is at first drilled in or punched out of the thin plate 6.
  • the prongs 4 are spread or rolled outwardly towards the corresponding rectangular openings 3 of the flange member 1 by means of any appropriate tool (not shown), which is not the subject matter of the present invention.
  • any appropriate tool can be applied for the attachment of the clinch nut to the plate 6.
  • Such tool may consist of a backing plate and a simple punch.
  • the tools may be adapted for use in a pair of parallel jaw pliers or a small press.
  • the clinch nut can be attached to the plate 6 by using a hammer, even Iby an unexperienced person.
  • the force required to roll over the prongs 4 is rather small, and even if the attaching operation is not entirely completed, the tightening of a bolt in the clinch nut will complete the attaching operation.
  • the clinch nut comprises again a flange member 1 of rectangular or any other suitable shape and has again a centrally disposed and axially extending open tubular portion 2 projecting from the top face of the flange member 1.
  • the flange member 1 has substantially rectangular openings 3 and prongs 4 extend from the tubular portion 2' in an axial direction opposite to that of the tubular portion 2 from ea'ch side of the center where the rectangular openings 3meet with the centrally disposed tubular portion 2.
  • a thread is cut into the inner face of the tubular portion 2 which thread 5' is adapted to receive a bolt having complementary outer thread.
  • FIGS. 7 to 11 a third embodiment of the clinch nut, designed in accordance with the presentinvention, has been disclosed, which is of a structure substantially identical with that of the second embodiment, as set forth above, with the exception that the nut itself is a separate member secured to the flange member by clamps to permit a rigid attachment or a floating attachment of the nutto the flange member.
  • the recess 92 is of a diameter substantially equal with the outer diameter of the tubular portion 22, in which case the nut member 82 is rigidly secured to the flange member 12 by means of the tubular portion 22 and the clamping projections 102.
  • FIGS. 15 to 20 a still further, 'fifth embodiment of the present invention is disclosed.
  • This embodiment discloses a quarter turn stud receiving means designed in accordance with the present invention.
  • This embodiment comprises a flange member 14 having a tubularA portion 24 as well as prongs 44 extending in a direction opposite to that of the tubular portion 24.
  • the flange member 14 has furthermore oppositely disposed rectangular openings 34. As indicated in FIG. 18, the flange member 14 is secured to a plate 64 by rolling over the prongs 44, in the same manner as in the previous embodiments.
  • the tubular portion 24 is open and has a dia'metrically opposite sides axial slots 114 (FIG. 16) and a diametrically -disposed groove 124, disposed apart from the axial slots 114 and ladapted to receive a bolt 134 having a head 144.
  • the bolt 134 has close to its face end a cross pin 154.
  • the bolt 134 extends through the bore 164 of another plate 62, which is to be secured to the plate 64.
  • a spring 174 is disposed between the head 144 and the plate 6a and has the function to retain the cross-pinv 154 in the groove 124 of the tubular portion 24, as indicated in FIG. 19 of the drawings.
  • the bolt 1314 is inserted into the tubular portion 24 in a position wherein the cross-pin passes through the slots 114.
  • the bolt 134 is then turned for 90 to set the cross-pin 154 into the grooves 124 and retained in this position by means of the spring 174 which engages lthe plate 6a and the head 144 of the bolt 134.
  • FIGS. 18 and 19 disclose a blade spring 174, while, in a variation thereto, a helical spring 174 is provided instead, as clearly shown in FIG. 20.
  • the clinch nut designed in accordance with the present invention has numerous advantages over the known structures.
  • the present clinch nut does not project beyond the plate 6 on the opposite side of the nut. Since the thickness of the prongs 4 is equal to the thickness or depth of the opening in the flange member 1, it permits the prongs 4 to deform a portion of the plate 6 into the rectangular openings 3 for an amount which is equal with the thickness of the prongs 4, thus formingL in the plate 6 a recess 3 and rendering the upper surface of the material of the plate 6 flush with the upper surface of the flange member 1. The total thickness of both the flange member 1 and the plate 6 does never exceed the combined thickness of both members.
  • the clinch nut is securely interlocked with the plate 6 against any torque action.
  • the clinch nut can be securely fastened i-n a round hole of a plate which is easy to form by drilling or by means of a round punch.
  • the clinch nut can be attached to very thin mate'- rial including synthetic material, such as plastic.
  • the prongs 4 provide also a guide for locating the nut in the bore of the plate 6.
  • the clinch nut can tbe used with bores in the plate having a greater tolerance, than it is possible in the known structures.
  • the spreading prongs will center the nut in the hole even if the bore is at the maximum tolerance.
  • it is also an inherent advantage of the present clinch nut that it will not pop out from the plate 6 or become loose, when the plate 6 to which it is attached is slightly bent.
  • a clinch nut comprising a flange member
  • said tubular portion including means for receiving a bolt therein, said ilange member having openings substantially diametrically opposite each other and dened on one side by a-n edge of the material of said ange member disposed tangential to said tubular portion, as well as extending substantially equally on opposites sides ⁇ of the point of tangcncy with said tubular portion,
  • prongs extending axially straight and directly from and integrally secured to said tubular portion in a direction opposite to that of said tubular portion at'the point of meeting of the tangential edge of said openings with said tubular portion
  • said prongs being substantially centrally located with respect to said tangential edge and said prongs being adapted to be fed through a hole of a plate, to which said clinch nut is to be attached, and said prongs to be turned over into said openings and clamping in the attached position said plate between said ange member and said turned over prongs, and
  • said prongs being of a width substantially less than the Width of said openings.
  • the clinch nut as set forth in claim 1, which includes clamping projections extending upwardly from opposite sides of said flange member and from the same side of said flange member as said tubular portion and spaced radially from said tubular portion with their ends overlying the end surface of the nut, in order to prevent axial displacement, and said tubular portion and said clamping projections cooperating to prevent lateral displacement, and
  • a nut member having a recess and engaging the top face of said ilange member an-d receiving said tubular portion in said recess thereof.
  • said nut member is welded to the top face of said ange member.
  • said means for receiving a bolt in said tubular portion comprises an end formation of said tubular portion which includes two -diametrically oppositely disposed axially extending slots and two crosswise disposed outer grooves set ott for about relative to said slots.
